The Claim

Higher dietary sodium intake is associated with an increased risk of cardiovascular disease, with each 1 gram per day increase in sodium intake linked to a 4% higher risk of cardiovascular disease and a 6% higher risk of stroke, based on pooled data from 21 meta-analyses that include both observational and randomized studies.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Eating more salt every day is linked to a higher chance of heart problems and strokes—every extra gram of salt per day raises your risk by a little bit, according to a big review of many studies.

What the research says

1 study
  1. Study: Dietary salt intake and cardiovascular outcomes: an umbrella review of meta-analyses and dose-response evidence

    This study found that eating more salt makes your heart and blood vessels work harder, raising your chances of heart disease and stroke — and for every extra gram of salt per day, your risk goes up by 4% for heart problems and 6% for stroke, just like the claim says.
